# --------------------( SYNOPSIS                           )--------------------
# Bash shell script wrapping this project's tox-based test suite, passing
# sane default options suitable for interactive terminal testing and otherwise
# passing all passed arguments as is to the "tox" command.
#
# This script is defined as a Bash rather than Bourne script purely for the
# canonical ${BASH_SOURCE} string global, reliably providing the absolute
# pathnames of this script and hence this script's directory.

# Array of all arguments with which to invoke Python.
#
# Note that the "-X dev" option enabling the Python Development Mode (PDM) need
# *NOT* be explicitly passed to "tox", as the ${PYTHONDEVMODE} shell variable
# in the "tox.ini" file already enables the PDM.

#FIXME: Excise us up, please. This no longer appears to be working as intended
#as has, in fact, obstructed sanity on multiple occasions.
# # Comma-delimited list of all tox environments. Dismantled, this is:
# #
# # * "tox -l", listing all environments defined by the "envlist" default.
# # * "grep linux", removing all duplicate platform-specific environments from
# #   that list.
# # * "paste ...", converting all newlines in that "grep" output into commas
# #   expected by the parent "tox -e" command.

# # Strip the optional "-coverage" suffix from these environments, preventing
# # tox from measuring coverage. While tox can be made to measure coverage at the
